中文摘要：
嘉峪关市生态环境容载力分析是建立环境友好型土地利用的重要理论基础,采用生态足迹-环境熵对嘉峪关市规划基期（2005年）的生态环境容载力进行定量分析,计算得出嘉峪关市2005年生态足迹的水平并与同期部分国家和国内部分地区进行比较,并对2001-2008年嘉峪关市的环境熵进行了实证分析,并进行了新陈代谢GM（1,1）建模,预测了规划末期（2020年）以内的环境熵演变趋势,最后提出支撑嘉峪关市经济社会发展对土地利用需求的生态环境保障对策建议。
英文摘要：
As one of the important early studies on the ＂general land use planning of Jiayuguan City（2006-2020）＂,eco-environment capacity analysis of Jiayuguan city was the key theoretical basis to establish environment-friendly land use pattern in an important theoretical basis.After the quantitative analysis of the ecological footprint of Jiayuguan city in the base period（in 2005） of the planning,the level of the ecological footprint of Jiayuguan city,in 2005,was compared with one of other countries and parts of our country during the same period,then the environmental entropies of Jiayuguan city from 2001 to 2008 was empirically analyzed,and the environmental entropy evolution trend during the planning period was forecasted by grey metabolism forecasting models GM（1,1） built.Finally,countermeasures and proposals about eco-environment protection to support the demand of land use for the economic and social development of Jiayuguan city were put forward.
